The book provides a bridge between the meaning of engineering end-use parameters of polyethylene resins (HDPE, LDPE, LLDPE, VLDPE) and their molecular characteristics. The main goal is to translate common end-use characteristics of the resins (melt index, density, melting point) or properties of standard items manufactured from the resins (dart impact strength and tear strength of film, top load of a bottle, etc.) into the universal language of the polymer science, average molecular weight and molecular weight distribution of a polymer, composition and a statistical description of a copolymer, parameters of the stress-strain curve of a semi-crystalline material, etc.
This book provides a necessary bridge between the values of engineering end-use parameters of polyethylene resins and their scientific molecular and structural characteristics. The main goal is to translate such common parameters, such as the melt index of a resin or the dart impact strength of a film sample, into the universal language of the polymer science. After this translation is completed, many facets of the resin properties became transparent and easily explainable.
